God said, “This is the sign of the covenant that I make between me and you and every living creature that is with you, for all future generations:
You shall circumcise the flesh of your foreskins, and it shall be a sign of the covenant between me and you.
The blood shall be a sign for you on the houses where you live: when I see the blood, I will pass over you, and no plague shall destroy you when I strike the land of Egypt.
It shall serve as a sign on your hand and as an emblem on your forehead that by strength of hand the Lord brought us out of Egypt.”
God said to Noah, “This is the sign of the covenant that I have established between me and all flesh that is on the earth.”
Now then, since I have dealt kindly with you, swear to me by the Lord that you in turn will deal kindly with my family. Give me a sign of good faith
I have set my bow in the clouds, and it shall be a sign of the covenant between me and the earth.
